The day this came in the mail, my mom had twisted her ankle and this really came in handy. I originally bought it for my stepfather because he previously broke both ankle bones and still suffers from foot pain. But since mom twisted her ankle, he was nice enough to let her use it and she said it really helped relieve the pain she was having so I say great product, does exactly what it was supposed to do. She also said it's very comfortable. I'd definitely purchase again!
